Abstract

A NICKEL POWDER HAVING A COMPOSITE OXIDE LAYER, COMPRISING LANTHANUM AND NICKEL AND OPTIONALLY CONTAINING AN OXIDE OF CHROMIUM, ON AT LEAST A PART OF THE SURFACE THEREOF. THE NICKEL POWDER IS PRODUCED BY A PROCESS COMPRISING THE STEPS OF: BRINGING A SOLUTION COMPRISING AT LEAST ONE HEAT-DECOMPOSABLE NICKEL COMPOUND AND AT LEAST ONE HEAT-DECOMPOSABLE LANTHANUM COMPOUND, AND OPTIONALLY CONTAINING AT LEAST ONE HEAT-DECOMPOSABLE CHROMIUM COMPOUND TO FINE DROPLETS; AND HEATING THE DROPLETS AT A TEMPERATURE ABOVE THE DECOMPOSITION TEMPERATURES OF THESE COMPOUNDS TO PREPARE A NICKEL POWDER AND, AT THE SAME TIME, TO DEPOSIT A COMPOSITE OXIDE LAYER COMPRISING LANTHANUM AND NICKEL AND, WHEN PRESENT, CHROMIUM OXIDE, IN THE VICINITY OF THE SURFACE OF THE NICKEL POWDER. THE NICKEL POWDER IS SUITABLE FOR USE IN A CONDUCTOR PASTE TO BE CO-FIRED WITH UNFIRED CERAMIC GREEN SHEETS FOR A MULTILAYER COMPONENT OR THE LIKE BECAUSE THE SINTERING INITIATION OF THE POWDER IS EFFECTIVELY DELAYED TO AROUND THE SINTERING INITIATION TEMPERATURE OF THE CERAMIC GREEN SHEETS, THEREBY PREVENTING THE PROBLEMS CAUSED DUE TO EXCESSIVE SINTERING.
